Title: Pilferproof container
Inventor: HONMA ICHIRO
IPC: B65D49/12
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To make an inner stopper unremovable by contriving so that nails, tools or the like is hardly available for catching on at the lower end of a skirt part by a method wherein the skirt part for fitting to a mouth of a container is formed at the outer circumference of the inner stopper, and a thin part is formed at the edge of the skirt part so that the thin part comes into contact with the outer circumference at a neck of the container. SOLUTION: An inner stopper 4 is formed of synthetic resin having a moderate flexibility, and its thin part 6 deforms when being attached to a mouth 2 and pressed in so as to be fit to a stepped part. Therefore, the thin part 6 is supported in the direction of radius at the stepped part 2b and becomes inflexible with an intensified strength against a force applied from the outside provided. With the stepped part 2b provided at a position right behind the thin part 6, an edged tool, even though being inserted between the inner stopper 4 and a container 1, can be inserted barely into a small depth. Therefore, an area for pushing up the inner stopper 4 by the edged tool becomes small, and a force sufficiently strong for removing the inner stopper 4 cannot be applied thereto.

Title: Dynamic pressure bearing motor, scanner motor and image forming device
Inventor: MINEGISHI SEI
IPC: G02B26/12
Filed: 1994-02-25
Abstract: PURPOSE:To prevent the leakage of dynamic pressure generated in a bearing with high air pressure generated in a cover member and to the reinforce the function of a dynamic pressure bearing by covering a rotation part with the cover member of a specified structure. CONSTITUTION:The rotation part 1 is covered by the cover member 10 which is fixed to a fixed part 4 and whose section inner size in the direction of a rotary shaft becomes gradually smaller with the distance from the fixed part 4. The cover member 10 is provided with an opening hole 11 of a circular shape on the end surface in the direction of the rotary shaft 3. At the time of rotation, air in the vicinity of the upper surface of the rotation part 1 entering from the open hole 11 to the cover member 10 is moved in the radial direction of the rotation part 1 by centrifugal force by the rotation of the rotation part 1. Then, the moved air is led in the direction of the fixed part 4, that is, downward the rotation part 1 by the tapered surface of the cover member 10. The air flow compresses the air of the lower part of the rotation part 1 to increase air pressure of the part, and since the vicinity of the rotary shaft 3 joint part of the rotation part 1 lower surface is held to the high air pressure generated in the cover member 10, the dynamic pressure is held higher without leaking the dynamic pressure generated in the bearing 6.

Title: Magnetic field generator
Inventor: KOBAYASHI NOBUTAKA
IPC: G01R33/387
Filed: 1993-01-22
Abstract: PURPOSE:To generate a highly uniform magnetic field in an MRI rectangular in a plane view by providing a magnetic flux shunting member comprising a magnetic material on the whole or a part of at least one side of a pair of permanent magnets CONSTITUTION:A line of magnetic force 24' emitted from around a side with flux shunting materials 22b and 22d of a magnet 14b enters the flux shunting materials 22b and 22d and is returned to the magnet 14b to form a loop. In other words, the flux shunting materials 22a and 22d are combined to allow the line of magnetic force to make a loop in stead of being attracted to a columnar yoke as in the past. As a result, the line of magnetic force of a magnetic field leaking near the side of the magnet appears evenly almost in a radial manner as viewed from above the magnet. This enables the lessening of a difference between the horizontal and vertical directions of the flow of the line of magnetic force emitted at the center of the magnet thereby enabling the obtaining of a highly uniform magnetic field within a spherical area.

Title: Production of compound semiconductor single crystal and apparatus therefor
Inventor: KAWASE TOMOHIRO
IPC: C30B27/02
Filed: 1987-02-10
Abstract: PURPOSE:To improve conversion rate into a single crystal, by changing the thickness of a liquid encapsulating agent layer in directly synthesizing a compound semiconductor raw material from a simple substance raw material of component elements thereof and pulling up the single crystal from the raw material melt. CONSTITUTION:A raw material of simple substance elements and a liquid encapsulating agent 9 are contained in a crucible 6 and the interior of a furnace body 1 is pressurized with an inert gas, such as N2, etc. A current is passed through a heater 4 to increase the heating temperature. Thereby the encapsulating agent 9 is initially melted to completely soak the simple substance element raw material. When the temperature is further increased, reaction is initiated to synthesize a semiconductor compound. Since the synthesized substance is a solid, it is melted by further increasing the temperature. In this state, an auxiliary shaft 13 is lowered to dip an annular vessel 14 in the encapsulating agent 9, which is then scraped into the vessel 14 to raise the auxiliary shaft 13. After the raw material melt 12 is subsequently stabilized at a single crystal growth temperature, the upper shaft 12 is lowered to compatibilize a seed crystal 10 with the melt 12 and the seed crystal is then pulled up.

Title: Method and system for locating surge on transmission line
Inventor: OOHIRA TAKESHI
IPC: G01R31/08
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a highly accurate surge location system for transmission line having relatively simple constitution. SOLUTION: At each surge receiving station, lines S, M indicative of the inclination off time variation rate in the time variation characteristics of surge are obtained. Since the surge received at each receiving station has different waveform because the distance from the location of surge to the receiving station is different, the lines S, M have different inclination. Difference of surge receiving time between the intersections of the lines and reference surge level lines C, D is then corrected.  Since the inclination of each line and the actual measurement of arriving time of surge at each station are known, difference of arriving time of surge at each station can be determined by correcting the arriving time difference due to the error time td (distance error) based on the difference of waveform for the reference surge levels C, D and the arriving time difference Δt±td of reference surge level is substituted, as an arriving time difference, to a locating equation in place of the arriving time difference Δt of zero level.

Filed: 1983-02-23
Abstract: PURPOSE:To obtain a pressure air for power or cleaning of polluted water as well as raise the effect of wave breaking by connecting plural air compressive chambers moved by vertical movement of waves in series to the lower part of a well-known break water. CONSTITUTION:Compressive chambers C1-C3 which are operated by the vertical movement of waves and put between a breakwater wall 2 and floats F1-F3, having valves V1-V4, are connected in series to the lower part of a well-known breakwater utilizing the resistance of a gentle slope face 1 of 30 deg.+ or -15 deg. to the water surface. During the descending process of waves, air of atmospheric pressure P0 enters from the valve V1 through a suction pipe 3 into the first compressive chamber C1. During the ascending process of waves, the suction valve V1 is closed, the exhaust valve V2 is opened, and the air compressed from the atmospheric pressure P0 to a pressure P1 enters a pressure storage chamber F1. When the pressure of the chamber F1 reaches the pressure P1, the exhaust valve V2' is opened, the air of P1 enters the second compressive chamber C2, and the actions are repeated until the final stage compressive chamber. Compressed air of the atmospheric pressure of 0.3-0.5kg/cm<2> can thus be obtained. When supplying the compressed air to the bottom under water, for example, the generation of red tide due to the shortage of dissolved oxygen can be prevented.

In this way, a rotating phase angle of two rotating bodies is obtained, and accordingly, the torque can be detected.
